As expected, it turns out that many of this summer's Big Brother 2015 housemates have been on telly before.

Before the group were unveiled at the weekend, ahead of Tuesday's launch in a Big Brother first, Bit On The Side host Rylan Clark had said that we might already have seen this year's lot.

But he insisted: "Even if they’ve been in the papers or on a show before, we select them because they’re going to be brilliant housemates.”

Amongst the housemates who have already been on the telly are 'kooky film director' Eileen Daly.

She appeared on The X Factor last year, making it as far as bootcamp, and has a whole list of other TV credits to her name from a Toyota advert to a spot in BBC One soap EastEnders.

Socialite twins Amy and Sally Broadbent meanwhile appeared on ITV2 reality show The Only Way Is Essex in 2013 where they were involved in quite the storyline with Mario Falcone and his then girlfriend Lucy Mecklenburgh.

Danny Wisker has also appeared on TOWIE as well as ITV2 dating show Girlfri3nds, which is hosted by Big Brother's own Emma Willis.

As a Model/Rapper/Singer/Athlete/Medical Student Cristian MJC, a.k.a. Matthew Clarkson is a quintuple-threat. He's even got his own Vevo page and music video, although with 13,000 views in 9 months it doesn't look like Cristian will be bothering the charts any time soon.

Now while some of the housemate line up may have already been in the limelight, others do seem shockingly normal for Big Brother.
